DESCRIPTION

IO::Pipe
provides an interface to creating pipes between
processes.

CONSTRUCTOR

new ( [READER, WRITER] )

Creates an IO::Pipe
, which is a reference to a newly created symbol
(see the Symbol
package). IO::Pipe::new
optionally takes two
arguments, which should be objects blessed into IO::Handle
, or a
subclass thereof. These two objects will be used for the system call
to pipe. If no arguments are given then method handles
is called
on the new IO::Pipe
object.

These two handles are held in the array part of the GLOB until either
reader
or writer
is called.

METHODS

reader ([ARGS])

The object is re-blessed into a sub-class of IO::Handle
, and becomes a
handle at the reading end of the pipe. If ARGS
are given then fork
is called and ARGS
are passed to exec.

writer ([ARGS])

The object is re-blessed into a sub-class of IO::Handle
, and becomes a
handle at the writing end of the pipe. If ARGS
are given then fork
is called and ARGS
are passed to exec.

handles ()

This method is called during construction by IO::Pipe::new
on the newly created IO::Pipe
object. It returns an array of two objects
blessed into IO::Pipe::End
, or a subclass thereof.
